Hi Claude, Thanks for replying. Only can't seem to find the solution in there. So the problem occurs on the apps that I've already built before and try to open. I tried installing one, and that works all fine. But when trying to open an old app, I get the error. A different message that comes up on the console when opening: signature state: Profile Missing, reason: Provisioning Profile Not Found So it has to be something with the certificate/bundleid/provisioning profile... That is not updated well with the apps. But I'm not so familiar with this... Thanks
